    Some old brick can be very weak. I seldom see bricks used as shims. I'm sure they usually work fine, but not if they are soft.

    Is it hard? In the photos it looks like it could be fiberglass. No saying it is.

    I agree that it looks like mainly a sanding problem. Differences in the way the wood accepts stain at areas that were drum sanded versus orbital sanded. At one area it looks like the contractor stopped the drum sander at the middle of the room, or did not wipe off the stain. I also think that getting good results with a very dark stain can be a bit tricky.

    I think the answer about cost savings is correct. The lower amperage main lighting breaker is less expensive. I recently bought 60 and 100 ampere circuit breakers and there was a significant price difference.

    I'm confused. Why is it not a downflow furnace with the AC coil on top? How would you do this with a standard furnace?

    I assume you mean combustion air supply? Yes, it is typically allowed.

    Everyone buying a house is concerned about squeaky floors. Nobody living in the houses seems to mind. Once you live in the house for a week or so you won't notice anymore.

    Sometimes a pipe is run quite a distance upstream and uphill. That creates a lot of head and apparently some of these can generate a significant amount of power. I am not sure how significant.

    I'm looking at the photo on my phone, so it is not real clear. The one streak seems to be aligned with an edge of the window. Maybe water penetration is washing out something. Do the streaks align with vertical joints in the siding?

    You should be able to remove the tile and mastic without damaging the subflooring, but it could be quite a bit of work. You can rent a grinder that will make it easier. Minor damage to the subflooring is not a problem because you will need to install an underlayment.

    Whether cutting or breaking is a better option would depend upon the profile of the concrete. If it is not too thick breaking would probably be fine. If it tapers back over a significant height, then cutting or drilling a lot of holes and breaking may be needed.

    I agree with the tight nailing. However, about a week ago I was walking around my neighborhood and saw the worst distorted vinyl siding on a wall that I have ever seen. No windows on that wall or the wall of the adjacent neighbor's house. There is a storage shed right next to the house with a black asphalt shingle roof. I assume that was the cause.

    Any idea what kind of wall sheathing? Any chance the siding is attached over furring strips?

    We have better looking barns in Pennsylvania than that house. Also, would a pier and beam foundation really last? Does treated wood resist WDIs forever?

    Check to see if the tile has been painted. I have seen similar cracks with painted tile.

    I think those are up around the Stanley Watras numbers.

    Circulator Layout

    mjr6550 replied to kurt's topic in HVAC Forum

    I think it works because the pumps push the water in the right direction so it does not have a reason to short circuit. Does this explanation make any sense?

    You might try contacting the product manufacturer to see if they have had any past experience with hail damage.
  19. mjr6550
    Yes to OSB.
  20. mjr6550
    Yes. The wires will probably carry current ok, but they are weakened and could break if disturbed. The fix is simple.

    This photo is from the back side of stucco removed from a wall. The WRB was #15 felt. The lowest temperature during the time period that it was probably installed was 45 degrees. Any ideas what caused this pattern. I was present when the stucco was removed from 28 townhouses and only about one wall on one unit looked like this. Click to Enlarge 65.3 KB

    I am looking at the photos on my phone. It appears that the strike was near the ground. I like how the current melted the pipe and left the coupling intact. Quite a few years ago my chimney was hit. Bricks flew about 150 feet.

    Interesting. I did not take the time to Google that, but I wonder how often that happens?
  24. mjr6550
    I would say that regardless of what you find in JLC, if its not in the code its not correct. Unless of course, the local AHJ says its ok. And that does not mean it is correct. I used an AAV to vent the kitchen sink in my island. I have not had any concerns in 2+ years. I know that some plumbers and inspectors don't like them, but they meet code and seem to work.

    Anything that is clay should be scoped. Around hear I think they stopped using clay commonly around the 1920s. Then went to cast iron. Any drain pipe that has a history of blockage should be scoped.
